Control systems determine the cutting path through CNC programs or graphic files and precisely control the movement of the laser head. The precision of path control directly affects the cutting outcome, requiring high-precision servo control capabilities.
2. Power Adjustment:
Control systems adjust the laser power based on the material properties and thickness to ensure cutting quality. The accuracy and stability of power adjustment are crucial for high-quality cutting.
3. Automatic Focusing:
During the cutting process, the distance between the laser head and the material must remain consistent. Control systems achieve this through automatic focusing, continually adjusting the laser head height to maintain a constant focal distance, thereby improving cutting accuracy.
4. Automatic Nesting:
The automatic nesting function efficiently arranges multiple cutting patterns on the material, maximizing material usage and reducing waste. This function not only increases production efficiency but also lowers material costs.
5. Real-Time Monitoring and Feedback:
Control systems use sensors to monitor various parameters such as temperature, pressure, and speed during the cutting process, providing feedback adjustments to ensure the stability and safety of the cutting process.
